(Cl. 229-37) -or ply wallcontainer which is made from a single blank Iand in which the number oflayers comprising the walls ofthe container is uniform throughout theirentire lengths.

The requirementrfor such a container exists for ship- Ament of objectsneeding protection but with a minimum weightr of box board in the' sidewalls of the container.

lNow, it is apparent that minimum thickness for protection can beprocured by using some prior art devices. ;However, in order to obtain abox of such minimum .thickness extensive additional thickness ofmaterial must be involved as the prior devices are not of uniformthickness. Of course, such prior constructions are therefore `needlesslycostly: First, in the sense that more material `than is actuallynecessary is used; and second, shipping ;costs may be needlessly highbecause of inclusion of use- 'less material in containers.

In accordance with the instant invention, the inclusion of funneces-sarymaterial in box construction can be obvviated.

It is an object of the instant invention to provide an .improvedconstruction in a multiple layered or ply wall v'carton or box in whichthe side walls are -of substantially `uniform thickness and providesubstantially uniform cushioning throughout their lengths and widths.

It is additionally an object of the invention to provide such a carton,box or container from a one piece scored blank.l

A yet further object of the invention is to provide aninexpensive-to-produce one piece multiple layered or ply wall shippingcontainer, by reason of minimizing use of material vvin the side wallsto that thickness and number of layers only which are in fact required.

The above and other objects, features yand advantages "of the presentinvention will become more apparent upon `consideration of the followingdescription and appende-d claims, whenconsidered in conjunction with theaccom- 'panying drawings, wherein the same reference characters ornumerals refer to like or corresponding parts throughout the severalviews.

FIG. 6 is a reduced plan View of the member which is shown in FIG. 5 andbeing after formation of the container side walls and before bending ofsaid side walls into final position.

Referring now more particularly to the drawings, it is believed that anunderstanding of the construction is more easily obtained by firsthaving reference to the blank from which the construction is formed. Theblank which is shown in FIG. 4 in plan view is preferably of corrugatedor equivalent fibrous board fabrication. It is seen that there are fourstraight rows which are herein identified by ,the letters A, B, C and D.While the rows A, B, C and D appear in the drawings extendedhorizontally, in the actual container construction the rows A, B, C andD are disposed vertically. Therefore, for the best understanding of howthe container will be formed, one must ment-ally rotate FIG. 4 90 l Now,having furtherreference-to FIG. 4, it is seen that there -arevninestraight columns which, in FIG. 4, extend-from side to side at rightangles to rows A, B, C and D. The columns are designated by the;numerals 10, 20, 30, 40, 50, 60, 70, and 90.

By thus identifying the rows and the columns, it is seen that thevarious sections which are divided by lines of scoring, numerals forwhich will hereinafter be applied, will conveniently have twocoordinates depending upon the row and the column in which each of saidsections falls. Accordingly, each of the sections is labeled in FIG. 4with its coordinates; and when speciiically referring to a particularsection in the instant description, such section will be defined orreferred to in terms of row and column coordinates.' In other words, forexample, all of the sections in row A, in addition to the numberdesignation depending uponthe column in which they are, have appliedadjacent such number designation the letter designation identifying therow A. f

The various blank sections heretofore identi-fied are in the most partdivided from each other by lines of scoring along which said sectionswill be creased or folded to formthe container. The lines of scoringdividing columns `10-90 are straight and parallel to each other.

The line of scoring between the column 10 .and Ztl-is designated by thenumeral 110. The line ofjscoring between columns 20 and 30 is identifiedby' the numeral 120. The line of scoring between columns 30 and 40 isdesignated by the numeral 130. -The line of scoring between the columns40 and 50 is designated by the numeral 140. That between the columns 50'and 60 -is designated by the numeral 150, The line of scoring betweenthe columns 60 and 70 is designated by the numeral 160. The line ofscoring between the columns 70 and Sil is designated by the numeral 170.And the line of scoring between the column 80 and 90 is designated bythe numeral 180. All are `as illustrated in FIG. 4.

Attention is especially invited to the lines of scoring 149 and 150. Itis observed that the line indicia employed to designate such lines ofscoring is different from the remainder of the scoring lines hereto-foreidentified. That is because lines 140 and 150 are distinctive in thatthey are reverse lines of scoring; that is to say, they provide forfolding or creasing which is in a direction opposite to or reverse ofthat for folding or creasing of the remainder of the lines of scoringheretofore identified between various columns 10-90.

`Between the rows A, B, C, and D and extending from the beginning ofcolumn 30 through column 70, there is a` plurality of additional linesof scoring. The additional lines of scoring are parallely to each otherand extend `transversely of lines of scoring -180. While such additionallines of scoring extend from side to side, that is, horizontally in FIG.4, nevertheless, they shall be referred to as vertical lines of scoring.

The said vertical lines of scoring are identified as follows: That whichis between the rows A and B is identied by the letter X; that verticalline of scoring which is disposed between or separates the rows B and Cis identified by the letter Y; that vertical line of scoring which isbetween or separates rows C and D is identied by the letter Z.

Between the blank sections A and 20A and 10B and B, there is a verticalslot 111 which in the blank appears as an extension of the line ofscoring X. Between the sections lllB and 20B and MC and 20C is a slot211 which appears as a vertical extension of the line of scoring Y.Between the blank sections 10C and 20C and 10D and 20D Ais an elongatedslot 311 which appears as a vertical extension of the line of scoring Z.On the opposite side of the blank, a slot 411 divides columns 80 andinto rows A and B, and said slot appears as a vertical extension of thevertical line of scoring A slot 511 divides columns 80 and 90 into B andC sections or rows, and said slot 5,11 appears as a vertical extensionof the vertical line Yof scoring Y. A slot 611 divides columns 80 and 90into Arows C and D, and said slot 611 appears as a vertical extension ofthe vertical line of scoring Z.

Having thus describedthe various components or blank sections and themeans separating them, itis appropriate that adescr'iption o'f thedimensions of the various components be provided as a tool to facilitatea more complete understanding of the invention. lFor orientation,

all dimensions employed in describing the invention will be in terms ofthe directions in FIG. 1.

Therefore, vertical will be a direction which extends from the top tothe bottom ofthe box in FIG. 1, and that dimension will be the one inwhich the height of the `device is reckoned. Whereas, width will be thedimension which extends perpendicular to the height in a Vertical plane,Such as the plane which is defined by the `lines of scoring Yand Z.Therefore, vthe shortest lineal distance between lines of scoring X andY would be considered the width Depth,' then, is the remainingdimension; in terms of FIG. 1 it may be characterized as distance in ahorizontal plane inward from a wall or vertical plane.

'Now, restated in terms of the `blank shown in FIG. 4, height is theshortest lineal distance between the lines `of scoring whichdivide theblank into columns 3), 449, 50, 60 and 7l). Width is .the shortestlineal dimension whichfdivides the blank 'into rows A, B, C and D.Whereas depth, and in this regard the only sections which have depthwithin the framework of the definition herein provided are the columns1t) and 2) and 80 and 90,

yis the shortest lineal distance between the edge 711 and the horizontalline of scoring 110, and also the shortest lineal distance between'theline 110 and the line of scoring 120. `On the other end of the device,depth is the shortest lineal distance 'between the lines of scoring 170and 180 and also between the line of scoring 180 and the other edge S11of said blank.

Now then, reference is had to the column 50. The height of each ofsections 50A, 50B, 59C and SilD is equal to twice the width thereof.The'width is considered vas one container construction unit. Therefore,each of sections. 50A, SGB, 50C and 50D may be characterized as havingan area of two square units of container construction.

With respect to the contains sections in the columns 30, dit, 60 and 70,the height of each of said sections is equal to its width, with thewidth of said columns equal to the width of column 50. Restatedtherefore, it may he be said that each of the sections A, 343B, 36C;36B, A, 40B, 49C, 46D, 63A, lB, 60C, 63D, 70A, 79B, 70C and 7ilD,comprises substantially a square, equivalent to one unit on each side,ergo an area of one square container construction unit.

Now then, reference is had to the columns 10 and Zit and 30 and 9) whichform the topof the box and the bottom of the box, respectively. Thewidth of each of sections lilA-llD, 20A-20D, SQA-86D and 90A-90D isequal to one full construction unit. On the other hand, the depth ofeach of said blank sections which will ultimately make up top and bottomvof the box is only equal to one-half a unit; that is, the depth of theblank lsections which comprise the top and bottom of the -box isone-half its width. Therefore, the area of sections 10A-10D, ZtA-ZQD,SGA-Stil) and A-96D each equals one-half a square construction unit.

Having thus described the details of construction and the preferreddimensions thereof, a description now ensues relative to the manner inwhich the blank is folded or creased and formed into the container orlbox seen in FIG. 1. It is believed that the most clear understanding ofthe ensuing description will be looking to the blank in FIG. 4.

In the rst step of the box formation, the portion of the blank comprisedof columns 1t), 26,36 and 4t) is bent upwardly toward the viewer andthen rotated clockwise downwardly upon the remainder of the blank alongthe reverse line of scoring 140. Next, that portion of the blankcomprised of columns 1t), 20 and 30 is bent upwardly toward the viewerand then rotated to the left or downwardly counter-clockwise along theline of scoring 134i, so that column 3) will be lying upon or superposedwith respect to column 4). Thereafter that portion of the blankcomprising columns 10 and 20 is Ibent downwardly with respect to FIG. 4at right angles to column 30 and along the line of scoring 120. Thencolumn y1t) is folded back or rotated counter-clockwise along the lineof scoring under the column 2li so that the free edge'711 engages thecolumn 3) adjacent the line of scoring 110.

Thereafter, that portion of the blank comprised of columns 60, 70, Siland 90 is folded upwardly with respect to FIG. 4 along reverse line ofscoring 150 and then rotated to the left or counter-clockwise untilcolumns 60 and 7o lie upon column 59. From such position, .but portionof the blank comprising columns '70, Si) and k9) is folded upwardlyalong the line of scoring andthen rotated downwardly to the right orclockwise to a position in which column '70 will lie or be disposed uponcolumn 6o. Then that portion of the blank comprised of columns 8i) andvSNL is `bent along the line of scoring 170 downward with respect toFIG. 4 to a position which is ,at right angles to column 70. Thereafter,column 90 is bent back `or rotated clockwise under column Ail() alongthe line of scoring so that the edge 811 engages the column 7) adjacentthe line of scoring 17,9.

The appearance of the construction to the `point just described is asillustrated in FIGS. 5 and 6.

In the final steps of the formation of the container or box, each of therows A, B, C and D is bent v90 from the adjacent thereof along arespective of the lines of scoring X, Y and Z. With the last bendingalong the vertical lin-es of scoring, the two vertical edges 911 and 912of the blank will be brought adjacent each other, as illustrated in thecross sectional view of FIG. 3.. A customary or conventional gummed tapeor the like may be employe to connect together the edges 911 and 912.

In the final stage of construction or formation, while the rows arebeing Vbent along the vertical lines of scoring X, Y and Z, thoseportions of the top which are comprired of sections 1GB and 29B and `10Dand 20D 'will be rotated beneath the sections 10A and 29A and sections10C and 20C. In like manner, sections 80B and 90B sections Stil) and91N) will be covered by the ,outer bottom portions comprised of sections80C and 90C and sections 30A and 90A.

From the foregoing, it is apparent that the formed container or box hasa heightfof 2 construction units and a width of l unit, so that the areaof each side of the box is 2 square units; and that the top and bottomof the box yhad by once againv are each 1 square unit comprising 1construction unit on each side thereof.

It is further observed that the multiple layered wall container herebyprovided comprises side Walls having throughout their area a uniformthickness of plural layers. The device provided by the instant inventionalso supplies a top and bottom of a uniform number of layers throughout,whereby the requirement for addition or provision of inserts to protecttops and bottoms of fragile objects or other fragile material and thelike is obviated.

As many substitutions or changes could be made in the above describedconstruction, and as many apparently widely different embodiments of theinvention within the scope of the claims could be constructed withoutdepart- Y ing from the spirit and scope thereof, it is intended that allmatter contained in the accompanying specification shall be interpretedas being illustrative and not in .a limiting sense.
